I am not sure how much you want to spend but 350 hp and 800 ft lbs is very do able. I would use a different programer box, 120 or 150 hp injectors, a small set of twins or a EFR turbo. Do you have a HX35 or a HY35 now? I like my muffler, the truck is loud enough. 4inch turbo back exhaust will be fine, and I like a low exhaust pipe to help keep the trailer cleaner, but to each his own. Gauges are mandatory, K&N filters have served me fine over the years but, you can run a one of the large paper air cleaners and not have issues with oil on the MAPP sensor. A improved lift pump is a must. You may as well break down and get a better Torque converter. And think about a shift kit. Is this truck 2 or 4 WD?
